- the Jimmy Twist also has at least one eyelet to stabilize the rod that is being screwed.
- Dowel Bar Substitute (DBS) or Dowel Bar Replacements (DBR) have been used in the construction industry for many years, and are typically specified to provide continuity and structural integrity in segmental concrete pour applications for reinforced concrete construction.
- the coupler/bar assembly is provided with an attached mounting plate. The assembly is, in turn, nailed or secured to the formwork. Once the form is set the externally threaded rebar is screwed into the exposed end of the coupler, creating a mechanical butt splice of two sections of reinforcing steel, and where the Dowel Bar Substitute (DBS) is normally rotated about four revolutions to securely mate at the mounting plate of the coupler.
- DBS Dowel Bar Substitute
- Dowel Bars are typically round steel bars which are used for providing a mechanical connection between slabs without restricting horizontal joint movement. These dowel bars have many applications, such as, for example, they are used in the jointed plain concrete pavement for carrying the added load and stress which are induced because, for example, due to the movement of vehicles. Although, the dowel bars are round steel bars, they are reinforced with a round deformation (rebar), especially for concrete applications. Additionally, in reinforced concrete pavements, dowel bars are typically used to transfer the load across the transverse joint from one pavement slab into the adjoining slab.
- U.S. Pat. No. 4,812,088 discloses a doweling tool for drilling a dowel hole in concrete to facilitate the insertion of dowels, the doweling tool having a guide bar, a support frame for supporting the tmide bar, a carriaue movingly connected to the guide bar, a pneumatically operated drilling tool having a drill bit connected to the carriage and a pneumatic cylinder having a portion connected to the support frame and another portion connected to the carriage.
- the pneumatic cylinder is operable to move the carriage and the drilling tool connected thereto in a forward direction for drilling the dowel hole and for moving the carriage and the drilling tool connected thereto in a reverse direction for withdrawing the drilling tool from the dowel hole.
- the carriage is rollingly supported on the guide bar by a roller assemblies for rolling movement in the forward and reverse direction.
- U.S. Pat. No. 6,502,359 discloses an expendable concrete dowel placement apparatus comprising a concrete form and a dowel holder capable of quickly positioning a dowel perpendicular to the surface of the concrete form, thereby allowing the finished concrete slab to expand and contract relative to a control joint without the dowel causing the concrete to yield.
- the concrete form maintains a plurality of square or rectangular apertures which receive the dowel bar holders.
- Each dowel bar holder maintains a plurality of retention clips and a located at its open proximal end which positively positions the dowel bar holder within the apertures of the concrete form in a position perpendicular to the front surface of the central vertical member of the concrete form.
- the concrete form is composed of a non-typical shape which allows the control joint to transfer loads to adjoining concrete slabs through the length of the control joint. Additionally, loads are transferred to adjoining slabs by the dowel or plurality of dowels located within the concrete slab.

- FIGS. 1 through 14 The inventive tool having a shaft with at least one adjustable wrench at one end of the shaft, and at least one handle at the other or opposite end of the shaft, and a method of using same will now be discussed with reference to FIGS. 1 through 14 .
- the invention namely, “The Jimmy Twist”, is an inventive tool that can be used to screw a rod, such as, for example, a threaded iron rod, into its desired location, such as, into a coupler.
- the inventive Jimmy Twist screws the DBS (Dowel Bar Substitute) into a coupler with ease.
- the Jimmy Twist is very easy, and quick to use, and is also very lightweight.
- the inventive Jimmy Twist saves an enormous amount of man hours when it is used to screws the DBS (Dowel Bar Substitute) into a coupler, while also saving the “backs” of the Reinforcing Ironworker, who has to manually screw the DBS (Dowel Bar Substitute) into a coupler, as in the past a standard adjustable pipe wrench was used, which did not easily grab the dowel rod, or would slip off the dowel rod, and which also did not provide any stability or torque assistance.
- a DBS rod goes through an eyelet in the Jimmy Twist, which allows for the top of the bar or rod to sit or rest at a stop. Then in a swinging motion using the handle, such as, a T-handle, an adjustable pipe wrench is used to catches the DBS a little above the DBS thread, such as, for example, say about 1 inch to about 2 inches above the DBS threads.
- the eyelet in the Jimmy Twist stabilizes the DBS bar, and so the Jimmy Twist tightens the DBS bar with ease.
- the Jimmy Twist will unscrew or unlatch quickly from the DBS bar, and is now ready to be used on the next or second DBS bar or dowel rod.
- the inventive Jimmy Twist is a tool that is designed to quickly and efficiently install DBS (Dowel Bar Substitute).
- a DBS is a piece of rebar with threads at one end that gets screwed into a coupler, which had been installed earlier.
- the Reinforcing Ironworker will remove a plastic cap from the coupler (the plastic cap keeps the coupler hole clean during the pouring of the concrete at the construction site), and then the operator starts screwing the DBS rod or bar into the coupler by hand, and then uses a standard pipe wrench to tighten it. So essentially this is a three-step process, namely, in step one, the user or operator would clear the coupler hole by removing the plastic cap, and then start to thread the rebar into the coupler using his hands. In step two, the operator would tighten the threaded rebar with a standard pipe wrench, and then in step three, the operator would torque the threaded rebar with a torque wrench to the desired or defined torque.
- the standard pipe wrench has to be adjusted multiple times to achieve the desired torque with the torque wrench to a specified torque, such as, for example: a Number 6 torque or % inch torque, or that the DBS bar has to be torqued to, say, about 130 pounds per foot, etc.
- a specified torque such as, for example: a Number 6 torque or % inch torque, or that the DBS bar has to be torqued to, say, about 130 pounds per foot, etc.
- the inventive Jimmy Twist is a quick on, quick off tool allowing for a full rotation of the DBS bar or rod in open spaces, or partial rotation in tight areas.
- the inventive Jimmy Twist cuts out the back breaking task of tightening, and torquing vertical DBS bar or rod while also cutting out almost two thirds of the time, if not more, to install the DBS bar or rod.
- the inventive Jimmy Twist basically comprises of a tool comprising of at least one turn handle, such as, for example, a T-handle, but the at least one turn handle could also be a L-shaped handle, a U-shaped handle, a wheel shaped handle, and combinations thereof, to name a few.
- the turn handle can be fixed on the inventive tool, or the turn handle can be attachable, and adjustable.
- At the bottom of the turn shaft there would be at least one bracket to securely attach the pipe wrench.
- the adjustable pipe wrench can be fixed, or bolted on, or welded, etc., onto the shaft of the inventive Jimmy Twist.
- the inventive Jimmy Twist is able to accommodate a #3 DBS, through a #11 DBS that are normally about two (2) feet long to about four (4) feet long.
- the inventive Jimmy Twist device is not limited to just a pipe wrench head, but of any apparatus that is used to successfully grasp rebar, turn rebar, and quickly release a rebar.
- Attachments such as, different size eyelets, and different size stops, comprising of any material suitable for task can also be used.
- Other attachments can also be fabricated to screw pre-bent steel, such as, pre-bent right angles, and pre-bent hooks, etc.
- the turn handle can also comprise of at least one ratcheting mechanism for less readjusting.
- the turn handle that is used for ratcheting can comprise of any shape, and material that is suitable for the job. For some applications a torque ratchet mechanism can also be used as an option.
- the adjustable wrench head can be secured, such as, by welding, using nut and bolt, or any quick release system, like for example, a quick release bolt.
- the inventive Jimmy Twist can be made to go in one direction (tightening), but also can be made to go bidirectional because mistakes are sometimes made, whether it is by the Reinforcing Ironworker, or a faulty coupler causing trouble, etc.
- the inventive Jimmy Twist makeup could also consist of pipe or cylinder comprising of any material where a notch is cut out and a gripping apparatus, such as, such as, a pipe wrench, is securely fixed.
- the inventive Jimmy Twist with its wrench grips the DBS bar for a smooth and an easy twist.
- the pipe or cylinder would stabilize the DBS, while offering a smooth, and easy twist.
- the turn handle for the inventive Jimmy Twist could be fixed, or detachable or adjustable.
- the turn handle could also be fitted with a drive socket. This drive socket would have to be centered over, or “plumb”, over the top of the DBS. This will allow for a smooth turn when using drive socket with drill, ratchet wrench, or any apparatus designed to turn a socket drive.
- the drive socket fixture could include, but is not limited to, the traditional square design, but to any shape, and any size drive system.
- the inventive Jimmy Twist could also have an attachment that fits an electric pipe threader, a special die adapter for the bigger bars when other methods or tools are not available. It should be understood that the attachment are not limited to just fit electric pipe threader but all types of pipe threaders, manual or electric.
- the pipe threader could be for example, of an octagon shaped “puck” with a square or any shaped drive hole that slides over top of the matching male drive on The Jimmy Twist which would allow the pipe threader to work as needed.
- couplers that are in use in the concrete construction industry, such as, for example, a coupler with parallel threads, where threads can be cut, rolled or forged.
- the first one uses reinforcing bars with the threaded portion having a smaller diameter than the rest, and a second type which uses bars with the threaded portion having a cross sectional area equal or greater than the nominal size.
- the first type is rarely used since the load capacity is reduced, while the second type maintains the parent bar load capacity and is widely used.
- An alternative to the first type also includes a variant where one end of a parallel threaded coupler is swaged onto a bar.
- the parallel or the first type coupler also has transitional and positional variants. The transitional coupler allows two bars of different sizes to be joined. While the positional coupler usually comprises two halves joined by a parallel thread with a lock nut arrangement.
- couplers with taper-cut threads which basically consists of an internally threaded metal coupler with a tapered thread, and a matching tapered bar. Due to its ability to meet the majority of the structural building applications it is popular.
- the standard tapered coupler can only be used in situations where the continuing bars can be rotated. This is not always practical and more sophisticated tapered couplers have been developed which allow the joining of bars that cannot be rotated, and the joining of bars where the continuing bar can neither be rotated nor moved (e.g. L-shaped bars).
- Another system comprises of couplers with integral threads over full length bar. These high yield reinforcing bars are specially manufactured with helical deformations along the full length of the bar. The deformations form a continuous coarse thread onto which an internally threaded coupler can be screwed. Locknuts are used at either end of the coupler to prevent slippage on the coarse threads.
- a turnbuckle system for when the continuing bar cannot be rotated is not available, but the coupler can be completely threaded onto one bar and then run back onto the continuing bar to form the joint.
- Another threaded coupler system uses swaging onto the ends of reinforcing bars.
- two malleable sleeves which are threaded internally for half their length are joined together by a high tensile threaded stud.
- the unthreaded parts of the sleeves are hydraulically swaged on the two ends of the bar to be joined. These ends can be screwed together using the threaded stud.
- the swaging process can be performed by the fabricator prior to arrival on site, in a stockyard at the site, or in-situ. For the latter method it must be ensured that there is sufficient working space around the bars. Connection of the bars with the threaded stud is performed in-situ.
- Another coupler system uses standard couplers which are designed to splice the same diameter bars where one bar can be rotated, and the bar is not restricted in its axial direction.
- the transition couplers are designed to splice different diameter bars where one bar can be rotated, and the bar is not restricted in its axial direction.
- the bolt couplers which provide a full-strength joint between a reinforcing bar and a standard metric bolt.
- the bolt coupler may be used for load-carrying steel structures bolted to concrete foundations, columns or walls, such as pylon bases, fixing crane rails, and fixings for heavy pipe work and walkways.
- These bolt couplers are machined from non-weldable grades of material but can be tack welded. They can make a convenient transition from reinforcing bar to metric threaded stud, maintaining the full strength of the bar. Transition is useful when forming long tie-bars, such as in formwork or pile-planks, against internal pressure, and to form a restraint anchor for ground anchors.
- the terminator coupler provides an alternative to hooked rebar, or an anchor or stop nut for rebar passing through a pile plank or structural steel element.
- the front face of the coupler is generously designed to carry the full tension load of the rebar when the anchor is bearing against concrete or structural steel.
- the transition rebar coupler is used to join two reinforcing bars of different sizes. It is commonly used for economic designs and columns where the diameter of the rebar reduces as the columns extend up the structure.

- the splice bars 10 , 20 are available in many configurations, such as, a straight splice bar 10 , 20 , with external threads 12 T, at one thread end 12 , or external threads 12 T, 14 T, at each thread ends 12 , 14 .
- the standard threaded rebar or rods 10 , 20 are normally about two (2) feet long to about four (4) feet long, and thus a worker or installer (not shown) has to go down to their knee level or bend down to install a rebar or rod 10 , 20 , that is normally between about two (2) feet long to about four (4) feet long.
- FIG. 2 further illustrates a standard threaded rebar coupler 25 , having a flange base 26 , where the rebar coupler or flange coupler 25 , has a coupler pipe or tube 28 , that is either welded or integrated with the flange base 26 .
- the flange base 26 has a plurality of holes or openings 27 , for the passage of a securing means 37 , such as, a nail 37 , a concrete nail 37 , a screw 37 , and combinations thereof, to name a few, that are used to secure the flange coupler 25 , 35 , to the site 17 , such as, a concrete site 17 .

The invention encompasses a Jimmy Twist which is an inventive apparatus comprising an adjustable wrench at one end of a shaft, a turn handle at the opposite end, and a method of using same. The turn handle, stop, eyelet, and wrench are all adjustable, while the turn handle is capable of rotating the attached shaft. The tool can be used to screw a rod, such as, a threaded iron rod, into its desired location, such as, into a coupler. The inventive Jimmy Twist allows the easy screwing of a DBS (Dowel Bar Substitute) into a coupler. The Jimmy Twist is very quick and easy to use, and is lightweight. The Jimmy Twist also has at least one eyelet to stabilize the rod that is being screwed.
- Dowel Bar Substitute (DBS) or Dowel Bar Replacements (DBR) have been used in the construction industry for many years, and are typically specified to provide continuity and structural integrity in segmental concrete pour applications for reinforced concrete construction. The coupler/bar assembly is provided with an attached mounting plate. The assembly is, in turn, nailed or secured to the formwork. Once the form is set the externally threaded rebar is screwed into the exposed end of the coupler, creating a mechanical butt splice of two sections of reinforcing steel, and where the Dowel Bar Substitute (DBS) is normally rotated about four revolutions to securely mate at the mounting plate of the coupler.
- Dowel Bars are typically round steel bars which are used for providing a mechanical connection between slabs without restricting horizontal joint movement. These dowel bars have many applications, such as, for example, they are used in the jointed plain concrete pavement for carrying the added load and stress which are induced because, for example, due to the movement of vehicles. Although, the dowel bars are round steel bars, they are reinforced with a round deformation (rebar), especially for concrete applications. Additionally, in reinforced concrete pavements, dowel bars are typically used to transfer the load across the transverse joint from one pavement slab into the adjoining slab.

Hake), the entire disclosure of which is incorporated herein by reference, discloses a doweling tool for drilling a dowel hole in concrete to facilitate the insertion of dowels, the doweling tool having a guide bar, a support frame for supporting the tmide bar, a carriaue movingly connected to the guide bar, a pneumatically operated drilling tool having a drill bit connected to the carriage and a pneumatic cylinder having a portion connected to the support frame and another portion connected to the carriage. The pneumatic cylinder is operable to move the carriage and the drilling tool connected thereto in a forward direction for drilling the dowel hole and for moving the carriage and the drilling tool connected thereto in a reverse direction for withdrawing the drilling tool from the dowel hole. The carriage is rollingly supported on the guide bar by a roller assemblies for rolling movement in the forward and reverse direction.
- U.S. Pat. No. 6,502,359 (Todd Rambo), the entire disclosure of which is incorporated herein by reference, discloses an expendable concrete dowel placement apparatus comprising a concrete form and a dowel holder capable of quickly positioning a dowel perpendicular to the surface of the concrete form, thereby allowing the finished concrete slab to expand and contract relative to a control joint without the dowel causing the concrete to yield. The concrete form maintains a plurality of square or rectangular apertures which receive the dowel bar holders. Each dowel bar holder maintains a plurality of retention clips and a located at its open proximal end which positively positions the dowel bar holder within the apertures of the concrete form in a position perpendicular to the front surface of the central vertical member of the concrete form. The concrete form is composed of a non-typical shape which allows the control joint to transfer loads to adjoining concrete slabs through the length of the control joint. Additionally, loads are transferred to adjoining slabs by the dowel or plurality of dowels located within the concrete slab.

FIGS. 1 through 14 . Although the scope of the present invention is much broader than any particular embodiment, a detailed description of the preferred embodiment follows together with drawings. These drawings are for illustration purposes only and are not drawn to scale. Like numbers represent like features and components in the drawings. - The invention, namely, “The Jimmy Twist”, is an inventive tool that can be used to screw a rod, such as, for example, a threaded iron rod, into its desired location, such as, into a coupler.
- The inventive Jimmy Twist screws the DBS (Dowel Bar Substitute) into a coupler with ease. The Jimmy Twist is very easy, and quick to use, and is also very lightweight.
- The inventive Jimmy Twist saves an incredible amount of man hours when it is used to screws the DBS (Dowel Bar Substitute) into a coupler, while also saving the “backs” of the Reinforcing Ironworker, who has to manually screw the DBS (Dowel Bar Substitute) into a coupler, as in the past a standard adjustable pipe wrench was used, which did not easily grab the dowel rod, or would slip off the dowel rod, and which also did not provide any stability or torque assistance.
- In summary a DBS rod goes through an eyelet in the Jimmy Twist, which allows for the top of the bar or rod to sit or rest at a stop. Then in a swinging motion using the handle, such as, a T-handle, an adjustable pipe wrench is used to catches the DBS a little above the DBS thread, such as, for example, say about 1 inch to about 2 inches above the DBS threads. The eyelet in the Jimmy Twist stabilizes the DBS bar, and so the Jimmy Twist tightens the DBS bar with ease. Similarly, in a reverse motion or swing The Jimmy Twist will unscrew or unlatch quickly from the DBS bar, and is now ready to be used on the next or second DBS bar or dowel rod.
- The inventive Jimmy Twist, is a tool that is designed to quickly and efficiently install DBS (Dowel Bar Substitute). A DBS is a piece of rebar with threads at one end that gets screwed into a coupler, which had been installed earlier.
- Traditionally, the Reinforcing Ironworker will remove a plastic cap from the coupler (the plastic cap keeps the coupler hole clean during the pouring of the concrete at the construction site), and then the operator starts screwing the DBS rod or bar into the coupler by hand, and then uses a standard pipe wrench to tighten it. So essentially this is a three-step process, namely, in step one, the user or operator would clear the coupler hole by removing the plastic cap, and then start to thread the rebar into the coupler using his hands. In step two, the operator would tighten the threaded rebar with a standard pipe wrench, and then in step three, the operator would torque the threaded rebar with a torque wrench to the desired or defined torque. Additionally, during the installation the standard pipe wrench has to be adjusted multiple times to achieve the desired torque with the torque wrench to a specified torque, such as, for example: a Number 6 torque or % inch torque, or that the DBS bar has to be torqued to, say, about 130 pounds per foot, etc.
- With the inventive Jimmy Twist, one can easily cut out the three steps from the traditional process as discussed earlier. The inventive Jimmy Twist is a quick on, quick off tool allowing for a full rotation of the DBS bar or rod in open spaces, or partial rotation in tight areas. The inventive Jimmy Twist cuts out the back breaking task of tightening, and torquing vertical DBS bar or rod while also cutting out almost two thirds of the time, if not more, to install the DBS bar or rod. This is due to the fact that the Reinforcing Ironworker does not need to bend over during the tightening of the DBS bar or rod, and this also saves him time and energy, and thus allowing the Reinforcing Ironworker to install more DBS bars or rods, compared to a Reinforcing Ironworker who is first using his hands, and then is using just a standard pipe wrench to fully, and properly tighten the DBS bar or rod.
- The inventive Jimmy Twist, basically comprises of a tool comprising of at least one turn handle, such as, for example, a T-handle, but the at least one turn handle could also be a L-shaped handle, a U-shaped handle, a wheel shaped handle, and combinations thereof, to name a few. Also, the turn handle can be fixed on the inventive tool, or the turn handle can be attachable, and adjustable. At the bottom of the turn shaft there would be at least one bracket to securely attach the pipe wrench. For some applications, the adjustable pipe wrench can be fixed, or bolted on, or welded, etc., onto the shaft of the inventive Jimmy Twist. The inventive Jimmy Twist is able to accommodate a #3 DBS, through a #11 DBS that are normally about two (2) feet long to about four (4) feet long.
- The inventive Jimmy Twist device is not limited to just a pipe wrench head, but of any apparatus that is used to successfully grasp rebar, turn rebar, and quickly release a rebar. Attachments, such as, different size eyelets, and different size stops, comprising of any material suitable for task can also be used. Other attachments can also be fabricated to screw pre-bent steel, such as, pre-bent right angles, and pre-bent hooks, etc. The turn handle can also comprise of at least one ratcheting mechanism for less readjusting. The turn handle that is used for ratcheting can comprise of any shape, and material that is suitable for the job. For some applications a torque ratchet mechanism can also be used as an option.
- The adjustable wrench head can be secured, such as, by welding, using nut and bolt, or any quick release system, like for example, a quick release bolt. The inventive Jimmy Twist can be made to go in one direction (tightening), but also can be made to go bidirectional because mistakes are sometimes made, whether it is by the Reinforcing Ironworker, or a faulty coupler causing trouble, etc. The inventive Jimmy Twist makeup could also consist of pipe or cylinder comprising of any material where a notch is cut out and a gripping apparatus, such as, such as, a pipe wrench, is securely fixed. The inventive Jimmy Twist with its wrench grips the DBS bar for a smooth and an easy twist.
- One could also use a device that would have any type of a turn handle which is suitable for task, and could easily slip over the DBS to be secured to the coupler. The pipe or cylinder would stabilize the DBS, while offering a smooth, and easy twist. The turn handle for the inventive Jimmy Twist could be fixed, or detachable or adjustable. The turn handle could also be fitted with a drive socket. This drive socket would have to be centered over, or “plumb”, over the top of the DBS. This will allow for a smooth turn when using drive socket with drill, ratchet wrench, or any apparatus designed to turn a socket drive. The drive socket fixture could include, but is not limited to, the traditional square design, but to any shape, and any size drive system. The inventive Jimmy Twist could also have an attachment that fits an electric pipe threader, a special die adapter for the bigger bars when other methods or tools are not available. It should be understood that the attachment are not limited to just fit electric pipe threader but all types of pipe threaders, manual or electric.
- For some applications the pipe threader, could be for example, of an octagon shaped “puck” with a square or any shaped drive hole that slides over top of the matching male drive on The Jimmy Twist which would allow the pipe threader to work as needed.
- Currently there are several types of couplers that are in use in the concrete construction industry, such as, for example, a coupler with parallel threads, where threads can be cut, rolled or forged. There are two variations to this type of coupler. The first one uses reinforcing bars with the threaded portion having a smaller diameter than the rest, and a second type which uses bars with the threaded portion having a cross sectional area equal or greater than the nominal size. The first type is rarely used since the load capacity is reduced, while the second type maintains the parent bar load capacity and is widely used. An alternative to the first type also includes a variant where one end of a parallel threaded coupler is swaged onto a bar. The parallel or the first type coupler also has transitional and positional variants. The transitional coupler allows two bars of different sizes to be joined. While the positional coupler usually comprises two halves joined by a parallel thread with a lock nut arrangement.
- Another coupler system includes couplers with taper-cut threads, which basically consists of an internally threaded metal coupler with a tapered thread, and a matching tapered bar. Due to its ability to meet the majority of the structural building applications it is popular. The standard tapered coupler can only be used in situations where the continuing bars can be rotated. This is not always practical and more sophisticated tapered couplers have been developed which allow the joining of bars that cannot be rotated, and the joining of bars where the continuing bar can neither be rotated nor moved (e.g. L-shaped bars).
- Another system comprises of couplers with integral threads over full length bar. These high yield reinforcing bars are specially manufactured with helical deformations along the full length of the bar. The deformations form a continuous coarse thread onto which an internally threaded coupler can be screwed. Locknuts are used at either end of the coupler to prevent slippage on the coarse threads. A turnbuckle system for when the continuing bar cannot be rotated is not available, but the coupler can be completely threaded onto one bar and then run back onto the continuing bar to form the joint.
- Another threaded coupler system uses swaging onto the ends of reinforcing bars. In this system two malleable sleeves which are threaded internally for half their length are joined together by a high tensile threaded stud. The unthreaded parts of the sleeves are hydraulically swaged on the two ends of the bar to be joined. These ends can be screwed together using the threaded stud. The swaging process can be performed by the fabricator prior to arrival on site, in a stockyard at the site, or in-situ. For the latter method it must be ensured that there is sufficient working space around the bars. Connection of the bars with the threaded stud is performed in-situ.
- Another coupler system uses standard couplers which are designed to splice the same diameter bars where one bar can be rotated, and the bar is not restricted in its axial direction.
- The transition couplers are designed to splice different diameter bars where one bar can be rotated, and the bar is not restricted in its axial direction.
- Another type of coupler are the bolt couplers which provide a full-strength joint between a reinforcing bar and a standard metric bolt. The bolt coupler may be used for load-carrying steel structures bolted to concrete foundations, columns or walls, such as pylon bases, fixing crane rails, and fixings for heavy pipe work and walkways. These bolt couplers are machined from non-weldable grades of material but can be tack welded. They can make a convenient transition from reinforcing bar to metric threaded stud, maintaining the full strength of the bar. Transition is useful when forming long tie-bars, such as in formwork or pile-planks, against internal pressure, and to form a restraint anchor for ground anchors.
- The terminator coupler provides an alternative to hooked rebar, or an anchor or stop nut for rebar passing through a pile plank or structural steel element. The front face of the coupler is generously designed to carry the full tension load of the rebar when the anchor is bearing against concrete or structural steel.
- The transition rebar coupler is used to join two reinforcing bars of different sizes. It is commonly used for economic designs and columns where the diameter of the rebar reduces as the columns extend up the structure.
